Sufficient CertaintyDeciding

Writing

On decision-making, the method, and what organisations get wrong when they try to manage "risk" instead of deciding.

Behavioral Decision Science Starts After the Syllabus

Your team already has the facts. Behavioral decision science earns its keep when it changes who can challenge the call, not when it names the bias.

Scenario Planning Framework for Decisions, Not Workshops

Most teams use scenario planning to map futures. A five-step framework shows your team which assumption to test before it commits.

Biases and Heuristics: Why Knowing Is No Cure

A heuristic can save time or trap your team. The cure is not naming the bias — it is testing the assumption the shortcut smuggled in.

Problem Framing Examples That Led to the Wrong Answer

Three real cases show you how to test the opening question before analysis locks in. You will leave with a plain-language framing check.

Lessons Learned Fail When Nobody Tracks the Assumption

Most organizations already run the lessons review. Use a simple test to tie each lesson to a failed assumption before your team repeats it.

Examples of Sound Judgment That Turn on One Assumption

Examples of sound judgment get real when a team tests the assumption carrying the call, not when it produces another board pack.

Enough Information to Make a Decision Is Not About 'How Much'

Your team has enough information already. One question reveals whether the decision is ready to make, or whether you are stalling for one more report.

Applied Decision Science Fails Before the Model Shows Up

Your team gets one owner for the decision and a recorded condition to reopen it. Applied decision science built from five real cases.

Art and Science of Decision Making: Why the Split Fails

Separating judgment from analysis costs organizations the decision itself. One discipline reunites them: state the assumption, then act.

Decision Record: The Part Every Template Leaves Out

Most organizations record the conclusion and skip the reasoning. A useful record names the assumptions a decision depends on and when to revisit them.

Avoid Analysis Paralysis Before the Meeting Starts

Paralysis comes from a process with no finish line, not from cautious people. Write down where that finish line is and the room stops spinning.

Team Decision Making Process Is Not Brainstorm and Vote

Most teams jump from ideas to a vote and call it done, but the decision was never tested. The fault is not the people. It is the process.

Decision Science vs Data Science: It's Not a Career Choice

One side builds the model. The other decides when it's good enough to act. Most people can't tell you which one they're missing.

Decision Coaching Process: Not One Big Workshop

The goal is not more discussion. A decision coaching process stops when the person who owns the call can actually defend it.

Scenario Planning Tools Miss the Only Question That Matters

Scenario planning tools model futures and display outputs. None of them force the team to name the assumption that would cancel the investment.

Business Problem Solving Starts Before the Business Case

A business case can have perfect numbers and still solve the wrong problem. Nobody checks the question until the money is spent.

Problem Definition vs Problem Solving Starts Too Late

Most teams start solving before anyone names the choice. The first sentence already picked the winner.

What Is Sound Judgment? It Starts With One Question

Sound judgment is not a gift. Every decision rests on a sentence nobody wrote down, and most people prefer it that way.

After Action Review Preserves the Original Mistake

After action review meetings replay events. The real mistake came earlier: the belief behind the call was never checked.

Sunk Cost Theory Still Leaves the Decision Unmade

The theory tells you why you kept going. It never tells you when to stop. That gap is where the money goes.

Confirmation Bias in Decision Making: Awareness Is No Cure

A first answer becomes protected property the moment challenge feels disloyal. A two-question test exposes confirmation bias before commitment.

Assumptions in Decision Making Are Mistaken for Facts

Only a few assumptions in decision making can break the outcome. Two questions show your team which beliefs rest on the thinnest evidence.

Sunk Cost Fallacy Investing: The Number in Charge

When the sunk cost fallacy runs an investment, the buy price becomes the exit plan. A two-question forward test replaces it with a checkable claim.

The Science of Decision Making Is Not More Analysis

The science of decision making starts with the assumption that must hold. Miss it, and more analysis only delays the call.

Creative Problem Solving Techniques Start Too Late

Creative problem solving techniques waste creativity on solutions first. The hard part is earlier: test the assumption hiding inside the problem.

Forecasting and Scenario Planning Both Dodge the Decision

Forecasting and scenario planning both avoid the real work. The question is simpler: what assumptions would have to hold?

Problem Framing Canvas Templates Launder the First Mistake

Most problem framing canvas templates start after the real mistake. Box one already has the sponsor's answer hiding inside it.

Halo Effect Bias: How Prestige Smuggles In Bad Decisions

Halo effect bias lets one admired trait carry claims it never earned. Strip the prestige and see what evidence actually survives.

The Sunk Cost Fallacy Is Not a Fallacy If This Is True

The sunk cost fallacy is not a real fallacy. Whoever called it one skipped the harder question.

Good Decisions Bad Outcomes. Bad Calls Get Rewarded.

Luck rewards sloppy reasoning and punishes careful analysis. The quality test sits in the assumptions behind the call, not the result.

Executive Decision Coaching Before the Board Pack Hardens

Executive decision coaching catches the weak call hiding in a strong paper. The room is about to lock it in. Nobody goes back.

Shell Scenario Planning Broke the Forecast Everyone Kept

Shell scenario planning never predicted the oil crisis. It broke the forecast everyone believed, and that mattered more.

Consensus Group Decision Making Fails Before the Real Test

Consensus group decision making fails when a room trades pieces of the answer for peace. The hardest objection is the one that should decide it.

Anchoring Bias: The Number Nobody Tested

Anchoring bias does not fade when you spot it. The first number sets the frame until someone calls it a guess.

Group Decision Making Techniques That Actually Decide

Group decision making techniques fail as workshop props. Run in sequence with a scheduled return, they drag the hidden bet into the open.

Sound Judgment in Leadership Starts With One Hard Question

Everyone wants it. Nobody tests the assumption behind the call. It stays hidden until the damage lands.

Overconfidence Bias in Decision Making Hides as Certainty

Overconfidence bias in decision making looks careful. The call feels settled before the proof is there, and process helps hide it.

When to Use Decision Coaching Before the Paperwork Decides

When to use decision coaching is clear after the old logic breaks. The papers are done, but the real call is still unmade.

Decision Consultant: What the Invoice Cannot Carry

Decision consultant sounds like someone who can carry the hard call. The analysis can be bought. The judgement cannot.

Reframing Problems When the Original Question Fails

Reframing problems is overdue once the facts no longer fit the question. The real miss is the question the room still wants to protect.

Representativeness Bias Mistakes Correlation for Causation

It worked before, so it must work again. That logic has emptied more accounts than bad luck ever did.

Choice Overload Starts Earlier Than It Looks

Choice overload does not start with option count. It starts when criteria sprawl and nobody can say what would be enough.

Problem Solving Skills in the Workplace Fail Earlier

Problem solving skills in the workplace get treated like talent. The miss comes first: nobody tests the belief carrying the choice.

Collective Decision Making Fails When No One Takes Ownership

Collective decision making may feel safer. But when nobody owns the decision, nobody fixes it when it breaks.

Problem Framing Techniques Most Teams Start Too Late

Problem framing techniques usually begin after the frame is set. The useful ones test Purpose in context before anybody starts fixing anything.

Post Mortem Analysis: A Decision-First Guide

Post mortem analysis usually stops at timeline and root cause. The useful review tests the assumptions that made the decision feel safe.

Hidden Cost Fallacy: The Quote Is the Easy Part

Hidden cost fallacy starts when the quoted price is treated as fact. The real cost sits in the assumptions nobody priced.

Overcoming Cognitive Biases Starts With One Question

Overcoming cognitive biases begins when a team names the assumption behind its answer. Awareness alone leaves the old error in charge.

Critical Uncertainties Scenario Planning Misses the Decision

Critical uncertainties scenario planning sorts what could change. It skips the one question that matters: which assumption breaks the decision.

A Collaborative Decision Making Model Needs One Decider

Most collaborative decision making models hand the call to a committee and lose it. One Decider and two blunt questions fix that.

Critical Thinking and Judgment: Why One Doesn't Fix the Other

Critical thinking sharpens analysis. Judgment calls the bet. Most courses teach the first and assume the second follows. It doesn't.

Psychological Biases Are Not What Kills Decisions

Psychological biases do not cause bad decisions. Hidden assumptions do. Test the assumption and the bias has nowhere to hide.

Sunk Cost and Decision Making: Judge the Next Decision

Sunk cost and decision making collide at HS2: GBP46.8bn spent, up to GBP58bn to cancel. The five steps that stop yesterday's money voting on tomorrow.

Effective Decision Making in Teams Starts Before the Meeting

Most team decisions fail before anyone talks. The boss hears yes, but nobody owns what happens next.

Decision Making Under Pressure: Calm Is Not a Method

Most advice says stay calm and trust your experience. Neither one is a method. The method has to be built before the clock starts.

Can Judgment Be Learned? Yes, but Only as a Method

Experience doesn't fix bad thinking. It just makes everyone too polite to say so.

The Framing Effect: Someone Already Chose Your Answer

Whoever writes the first draft picks the winner. Experience will not catch it. A simple rewrite will.

Judgement and Decision Making Are Different Jobs

Judgement and decision making are not the same job. One tests what a choice rests on; the other owns the whole process around it.

Problem Solving Examples in the Workplace Go Wrong Early

Four problem solving examples in the workplace where teams solved the wrong problem because nobody questioned the opening assumption.

Types of Cognitive Bias That Matter in Decisions

Most types of cognitive bias describe how minds misfire. Sort them by where they break a decision and you can actually catch them.

Cognitive Bias Examples That Wreck Decisions

Cognitive bias examples from Flint to NASA where every decision looked reasonable inside the room. Each one skipped a checkpoint no one asked about.

How to Develop Sound Judgment on Purpose

Your team already makes judgment calls. Sound judgment is the difference between trusting the assumption and testing it before the room commits.

Problem Solving Techniques in Business Start Too Late

Problem solving techniques in business miss the step before the first step. A study of 100 diagnostic errors found it was the single most common failure.

Sunk Cost Bias: Why Past Losses Feel Like Present Evidence

Sunk cost bias turns past losses into fake evidence for staying the course. Once dead money acquires a moral voice, boards defend work nobody believes in.

Scenario Planning Examples That Actually Changed Decisions

Oregon doubled transit funding after scenario work. Britain rehearsed a pandemic and changed nothing. These scenario planning examples show the difference.

Problem Solving in the Workplace Starts With the Decision

85% of 106 C-suite executives told HBR their organisations misdiagnose problems. The meetings were not short of discussion. They were short of a decision.

Problem Solving and Decision Making Are Not the Same Job

Most teams solve problems all day and never make a decision. The two jobs look alike but fail differently.

Groupthink in Decision Making Is Structural, Not Personal

Groupthink in decision making survives because the process never asks who disagrees. One structural change eliminates it before the meeting even starts.

Availability Bias in Decision Making: Memory Is Not Evidence

Availability bias makes the most memorable danger feel like the most likely one. Decisions built on that mistake cost lives and money.

Analysis Paralysis Examples: What Respectable Process Hides

Five analysis paralysis examples where the process looked thorough and the assumption underneath went untested.

Complex Problem Solving Starts With One Decision

Complex problem solving fails when everyone discusses the problem and nobody writes down the decision it requires.

Decision Making Process Model: Why Selection Is the Midpoint

Most decision making process models end at selection. That is the midpoint, not the finish.

Effective Decision Making in Leadership Is Structured Work

Effective decision making in leadership is not about looking confident. It is about saying what you believe and checking before anyone else pays the price.

Data Paralysis Starts When Data Pretends to Decide

Data paralysis starts when dashboards give you confidence without clarity. The real question is not what the data says but what it leaves out.

Business Decision Analytics Under Uncertainty

Business decision analytics under uncertainty shows you the choices. It does not make the choice. A person still has to own what the numbers miss.

Decision Making Models Are Not One Thing

Decision making models solve different problems. Using the wrong type means the model runs and the decision still drifts.

The Effects of Analysis Paralysis Are Worse Than Delay

The effects of analysis paralysis go deeper than delay. The real damage is when paper activity starts to look like prudent management.

Making Difficult Decisions as a Leader

Making difficult decisions as a leader feels high-stakes because you treat every call as permanent. Most are not, and that changes everything.

Decisiveness in Leadership Is Not About Speed

Decisiveness in leadership means knowing what you are betting on before you commit.

Strategic Decision Making for Leaders Uses the Same Method

Canada Post lost $4.5 billion since 2018 defending a strategy nobody re-examined. One structural change would have caught the drift years earlier.

RAPID Decision Making Framework: Roles and Limits

RAPID clarifies who decides. It doesn't test whether the decision is sound. Here's what it does well, and the step it skips.

Decision Making Process Under Uncertainty

After 6.8 million Janssen doses and six clotting cases, the CDC knew enough to pause in one day. Most boards still cannot say what enough looks like.

Decision Model: Useful Until It Takes Over

Decision model outputs look objective until you notice the judgement baked into every input. That gap is where decisions quietly fail.

Decision Making Under Uncertainty Example Cases

Apollo 13 had 87 hours and brought the crew home. Blockbuster had ten years and lost 9,000 stores. The cause of failure was never time pressure.

When Decision Analysis Becomes Camouflage

SVB had stress tests and interest-rate models. Depositors still pulled $40 billion in a day. The analysis had become camouflage for a preferred answer.

Facts Alone Cannot Close a Decision

Ariane 5 reused an Ariane 4 routine. Forty seconds after lift-off, an overflow killed the guidance system. Nobody had tested the inherited bet.

Indecision at Work Is a Process Failure, Not a Character Flaw

A restructure sat on a manager’s desk for three months. Two consultant reports. Four meetings. She already knew the answer. The process had no exit.

Every Stalled Decision Is Missing a Stopping Rule

One public safety body spent 99.97% of its budget on deciding and 0.03% on doing. Nobody in the chain had authority to call a halt.

Decision Making Coach: Simple Questions, Not Frameworks

A decision making coach works on one live choice, not broad development. What the role involves and how it differs from life coaching or consulting.

Too Many Choices Paralysis Is a Purpose Problem

The jam study is real but misapplied. Too many choices paralysis is caused by skipping one step, not by the number of options. That step changes the meeting.

Decision Rights Framework: Why the Right Person Gets It Wrong

A decision rights framework maps who recommends, who approves, and who has final authority. This guide explains how it works — and why assigning the right person still isn't enough.

Decision Making Under Deep Uncertainty

Decision making under deep uncertainty cannot be rescued by better models. When the range of futures is unknowable, judgment is the method, not the fallback.

Decision Fatigue Research: Which Findings Replicated

Decision fatigue research built 600 papers on four lab studies. The brain-as-battery model did not replicate. Here is what the evidence still supports.

Decision Fatigue vs Analysis Paralysis: Same Root Cause

Gartner found B2B buying groups average six to ten people. Each added person drains the individual and stalls the group. Same apparatus, two symptoms.

Decision Coaching vs Consulting

A board chair had a 96-page report recommending a sale. He still asked: what exactly am I being asked to decide? That is the gap consulting cannot close.

What Is Decision Coaching? A $5B Industry Left It Out

Decision coaching is structured help for one live choice, not months of development. How the role works and why a $5B industry still skips it.

Decision Fatigue at Work Is a Process Problem

Zhang Ruimin cut 12,000 managers from Haier's 80,000-person workforce. Sanyo's losses reversed in eight months. The hierarchy was delay, not governance.

Analysis Paralysis in Business Is Not a Leadership Failure

Citibank spent twenty-two years reviewing an obsolete system. A contractor clicked the wrong box and wired $900 million. The governance record was perfect.

How to Overcome Analysis Paralysis: Stop Asking for More Data

Analysis paralysis runs on one move: making the next report feel urgent. The assumption underneath never gets tested.

How to Overcome Decision Fatigue: Sleep Won't Fix It

Decision fatigue comes from the process, not the person. Meetings and approvals wear people out before anyone asks the real question.

Decision Fatigue Examples the Standard Advice Cannot Explain

NASA, NHS Mid Staffs, Carillion, Wells Fargo: four decision fatigue examples where full governance was in place and still failed to produce a decision.

Is Decision Fatigue Real?

Decision fatigue is real as an experience. The mechanism behind it is not. Three replications killed ego depletion. Process exhaustion is what breaks decision-makers.

What Analysis Paralysis Really Means

Nokia's engineers knew Symbian would fail. Seven years later, Microsoft bought the mobile division. Forty percent market share, gone.

Executive Decision Fatigue Is Not About Too Many Decisions

Executive decision fatigue looks like overwork. Every hour went to the process. None went to actually deciding.

Making Decisions with Uncertainty

Sullenberger had 208 seconds between engine failure and the Hudson River. All 155 survived. The six-month boardroom version uses the same method.

The Decision Autopsy

Fairfax Media operated for decades on one assumption nobody wrote down. A decision autopsy would have caught it five years before the sale.

Risk Registers Don't Help You Decide

Enron had one. Boeing had one. The Australian banks had dozens. The risk management apparatus was fully assembled and fully useless when it mattered most.

How To Make a Difficult Business Decision Without More Analysis

Most difficult business decisions are not short on data. What they lack is simpler: the assumption no one tested.

Vale Roger Estall

A tribute to Roger Estall, co-author of Deciding, who through his advocacy for fire safety saved more lives in New Zealand than anyone else. 21 June 2023.

Decisions Without Risk Management

A billion-dollar acquisition assumed foreign regulators would match domestic speed. A shift roster assumed workers would self-manage rest. Same error, same fix.

Conversations with Mark Siwik

From BHP Billiton to the ISO working groups that produced ISO 31000, and why the standard he helped write cannot help anyone actually decide.

Why the IIA Three Lines Model Fails

The IIA Three Lines Model draws lines on a chart and calls it governance. None of those lines ask whether the decisions are any good.

COSO ERM in a COVID-19 world

Why enterprise risk management frameworks did not and could not help organisations decide what to do about COVID-19. The pandemic proved the apparatus useless.

Should Internal Audit Assess Risk?

Manufacturing solved this decades ago: stop inspecting finished products, build quality into production. Internal audit still inspects the output.

The Risk Management Millstone

The first ISO risk management standard needed 29 special labels and five contradictory notes just to define its own core term. That tells you everything.

What Is a Decider? The Role Most Organisations Overlook

Every organisation has people whose choices determine outcomes. Most have no way to identify them or equip them. The Decider role fixes that.

Why Every Decision Starts with Purpose

A mining company in Western Australia nearly committed $200 million before anyone asked whether the community had consented. Nobody had checked.

How to Monitor Your Decisions

A tailings dam ran for a decade on original rainfall figures. Climate had shifted. The design tolerance was already exceeded when someone finally checked.

Anticipating Disruption

When COVID-19 hit, no organisation opened its continuity binder. They just decided. The apparatus they had spent years building sat on the shelf.
